Influence of Vapor-Liquid Two-Phasen-Heptane on the Explosion Parameters in Air

Abstract

Potential explosion hazards arising from releases of natural gas are now reasonably well understood, but the hazards exhibited by vapor-liquid two-phase (mist) mixtures are often overlooked. This work aims at providing new experimental data on the influence of the particle size of liquid phase n-heptane on the explosion parameters in vapor-liquid twophase n-heptane/air mixtures. A series of experiments was carried out as follows: First, at the mean Sauter mean diameter of 12.16 μm and 21.23 μm, two sets of vapor-liquid twophase n-heptane/air mixtures of various concentrations was obtained. Subsequently, experiments were implemented on the explosion pressure and the explosion temperature on two sets of various concentrations of the vapor-liquid two-phase n-heptane/air mixtures. The lower flammability limits and the minimum ignition energies were analyzed.

A Comparative Study of the Explosion Characteristics of IPN and IPN/JP‐10 Mixtures in Air Aerosols

“…Experiments were performed in the cylinder explosion vessel using central ignition, which was achieved using an inductive-capacitive spark produced between tungsten electrodes with rounded tips and separated by a spark gap of 3 mm. The setup can also be found in previous references [5,[29][30][31][32]. The measurements of the droplet size distribution and concentration were based on Mie scattering.…”
